Access control valve SUPER STARS ST-VC3
Angle Service Valve SUPER STARS ST-VC3 – Low-Loss Charging
Professional service valve for low-loss charging and recovery of modern HVAC and refrigeration systems.
The SUPER STARS ST-VC3 is an angled service valve designed for low-loss charging and evacuation of refrigeration and air conditioning systems using refrigerants such as R410A, R32, R290 and other HVACR refrigerants. The valve is equipped with a 5/16" SAE female thread on the system side and a 5/16" SAE male thread for connection to a service hose.
By turning the control knob, the internal plunger mechanism opens the system access valve, allowing controlled refrigerant flow to or from the service hose. This design significantly reduces refrigerant loss during charging or recovery operations, in compliance with European regulations aimed at reducing F-gas emissions.
Key Features
- Low-loss charging – minimizes refrigerant loss during service operations.
- Angled design – ideal for compact and hard-to-reach service ports.
- Plunger mechanism – precise opening of the system access valve.
- PTFE (Teflon) seals – high chemical resistance and long service life.
- 5/16" SAE full compatibility – designed for modern HVAC systems.
- Professional-grade construction – suitable for intensive service use.
